What does interdependency mean?
Interdependency is the condition of being mutually dependent. It describes a relationship in which people, organizations, institutions, or natural systems rely on one another for support, resources, stability, or survival. The idea is especially important in economics, politics, ecology, science, and technology, where large-scale systems function through networks of reciprocal relationships. Interdependency is stronger and more specific than simple dependence: it usually implies that the parties involved affect one another and cannot be fully understood in isolation. For example, national economies are interdependent because trade links them, while ecosystems depend on the interaction of organisms and environmental conditions. The word can carry either a neutral descriptive meaning or, in political discussion, suggest vulnerability arising from close reliance on other people or systems. Understanding interdependency helps explain why cooperation, communication, and collective action are often necessary when dealing with complex global problems.

Where does interdependency come from?
Interdependency is formed in English by combining the prefix inter-, meaning “between” or “among,” with dependency. Dependency comes through Latin dependere, from pendere, “to hang,” and originally conveyed the sense of being suspended from or subordinate to something else. The prefix inter- makes the relationship reciprocal: the dependence is not one-sided but exists between the participants.
